Question

我有一个包含GCM服务的程序，GCM服务在我的某些设备上表现完美

，包括：

1）android模拟器（Google API 17 - 4.2.2）

2）LG手机（Android 4.1.2）

3）谷歌手机（Android 4.2.2）

但是，在以下设备上，似乎GCM功能在注册状态时停止 onRegistered()未被调用。

包括：

1）索尼（Android 4.0.4）

2）HTC（Android 4.0.3）

3）三星平板电脑（Android 3.0.3）

由于它可以在我的某些设备上运行，我很确定问题不在我的代码或Android清单权限设置中，但我不知道我可以添加或修改什么来解决这个问题。

我知道版本4.0.4及更低版本的GCM功能需要一个活跃的Google帐户，但我尝试了它并且它仍然无法正常工作。同时我尝试了这两个问题中提出的解决方案，但没有帮助

I can not get registration ID from Android GCM

Android GCM : GCMRegistrar gives empty registration ID

任何人都可以给我一些建议如何解决这个问题？我可以通过其他任何方式执行服务器推送通知功能吗？

这是我的代码

    //GCM part
    cd = new ConnectionDetector(getApplicationContext());

    // Check if Internet present
    if (!cd.isConnectingToInternet()) {
        // Internet Connection is not present
        alert.showAlertDialog(this,
                "Internet Connection Error",
                "Please connect to working Internet connection", false);
        // stop executing code by return
        return;
    }

    // Getting name, email from intent
    Intent i = getIntent(); 

    // Make sure the device has the proper dependencies.
    try{
        GCMRegistrar.checkDevice(this);
        // Make sure the manifest was properly set - comment out this line
        // while developing the app, then uncomment it when it's ready.
        GCMRegistrar.checkManifest(this);
    }catch(Exception e){
        Toast.makeText(getApplicationContext(), "Version too old" + e.toString(), Toast.LENGTH_LONG).show();
    }
    registerReceiver(mHandleMessageReceiver, new IntentFilter(
            DISPLAY_MESSAGE_ACTION));

    // Get GCM registration id
    final String regId = GCMRegistrar.getRegistrationId(this);
    // Check if regid already presents
    if (regId.equals("")) {
        // Registration is not present, register now with GCM           
        try{
            GCMRegistrar.register(this, SENDER_ID);
            Toast.makeText(getApplicationContext(), "Trying to register", Toast.LENGTH_LONG).show();
        }
        catch(Exception e){
            Toast.makeText(getApplicationContext(), "Registration failure", Toast.LENGTH_LONG).show();
        }
    } else {
        // Device is already registered on GCM
        if (GCMRegistrar.isRegisteredOnServer(this)) {
            // Skips registration.              
            Toast.makeText(getApplicationContext(), "Already registered with GCM", Toast.LENGTH_LONG).show();
        } else {
            // Try to register again, but not in the UI thread.
            // It's also necessary to cancel the thread onDestroy(),
            // hence the use of AsyncTask instead of a raw thread.
            final Context context = this;
            mRegisterTask = new AsyncTask<Void, Void, Void>() {

                @Override
                protected Void doInBackground(Void... params) {
                    // Register on our server
                    // On server creates a new user
                    ServerUtilities.register(context, userId, "123", regId);
                    return null;
                }

                @Override
                protected void onPostExecute(Void result) {
                    mRegisterTask = null;
                }

            };
            mRegisterTask.execute(null, null, null);
        }
    }

还有Manifest

<!-- Permission to vibrate -->

<application

     <receiver

        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>

            <!-- Receives the actual messages. -->
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <!-- Receives the registration id. -->
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="com.test.activity" />
        </intent-filter>
    </receiver>

    <service android:name="com.test.activity.GCMIntentService" />

Answer 1

我不确定它是否与您的问题有关，但是这个：

<uses-permission android:name="com.test.activity.C2D_MESSAGE" />

应改为：

<uses-permission android:name="com.test.activity.permission.C2D_MESSAGE" />

GCM功能仅在少数设备上获取注册ID
